Lachlan Murdoch’s supermodel wife Sarah enjoys day out at Sydney Easter Show

Lachlan Murdoch’s model wife Sarah is certainly making the most of her new life in Sydney, Australia.

The couple and their three children quietly arrived Down Under from Los Angeles last month, amid claims Joe Biden taking power made things ‘rough’ for the family.

And on Good Friday, the mother-of-three decided to celebrate the holidays by treating her children to a day at the Sydney Royal Easter Show, at the city’s Olympic Park.

Sarah, 48, looked effortlessly stylish in form-fitted jeans and a white button-up shirt.

She blended in with the crowds in her understated look, teaming her ensemble with a pair of Lowe ballet runners, in nylon and calfskin, valued at $820.

The former Australia’s Next Top Model host wore her hair in a casual wavy style, and appeared to wear a touch of makeup to enhance her features.

Under her arm, she was seen carrying a haul of showbags and chocolates in a bag for her children.

The Sydney Royal Easter Show is Australia’s largest annual ticketed event, which attracts hundreds of thousands of attendees each year to celebrate the country’s rural traditions to modern day lifestyles. 

There’s an array of rides, animal and wildlife showcases, competitions and food and drinks for the whole family to enjoy.

It’s believed Sarah attended the event with her sons Kalan Alexander, 16, Aidan Patrick, 14, and daughter Aerin Elisabeth, 10.

Sarah and Lachlan, the man most likely to take over his father Rupert’s global empire, and their offspring arrived in Australia in March via private jet.

While no reason was given for the family’s return Down Under, a new report claimed that it was the political climate in the US that helped make the decision for the family to leave LA in favour of their Sydney home.

According to the Sydney Morning Herald, the family ‘felt the cold winds of political change’ when Joe Biden assumed power over Donald Trump, after the family-owned Fox News appeared to favour the Republican Party throughout the election campaign.

The publication also claimed things ‘got pretty rough’ for their children at school.

A source said: ‘The school communities here are very close knit, and it extends into the wider families and the circles and parties they all go to. That Hollywood set is very pro-Democratic.

‘They are mostly big fundraisers for Biden, so you can imagine how well it went down when one of their classmates’ dads is at the helm of the biggest anti-Biden machine in the country.’

Daily Mail Australia has reached out to News Corp for further comment. 

The family completed the mandatory quarantine period for international visitors by remaining confined to their luxury home in Sydney’s eastern suburbs.

The Murdochs bought the beautiful Georgian mansion in Sydney’s Bellevue Hill in 2009 for $23 million and then reportedly spent $11.67million renovating the property.

They also purchased an adjoining property for more $4.4million in 2018. In the current Sydney market, the estate would be worth closer to $50million.

Despite their life in Los Angeles, where Lachlan is Executive Chairman and CEO of Fox Corporation, the couple has always maintained the home in Sydney, where they first met in the late 1990s before marrying in 1999.

It’s not known how long the glamorous family plan to stay in Australia, although a large 90th birthday for patriarch Rupert is said to be planned for July this year in California.
